Scream
Rules to succesfully survive a horror movie:
You may not survive the movie if you have sex.
You may not survive the movie if you drink or do drugs.
You may not survive the movie if you say "I'll be right back", "Hello?" or "Who's there?"
Scream 2
Rules to succesfully survive a horror movie sequel:
1. The body count is always bigger.
2. The death scenes are always much more elaborate, with more blood and gore.
3. Randy starts to describe the third rule: "If you want your films to become a successful franchise, never, ever...' before being interrupted by Dewey. However, the film's original teaser trailer featured an extended version of the rules scene which reveals that originally the third rule was supposed to be "Never, ever, under any circumstances assume the killer is dead." This referenced Randy's last line in the first Scream which stated that a killer always comes back to life for one last scare.
The lack of a third rule in the film's final cut was a deliberate in-joke by the crew.
Scream 3
Rules to succesfully survive the last chapter of a horror movie trilogy:
1. You've got a killer who's gonna be superhuman. Stabbing him won't work, shooting him won't work. Basically in the third one, you gotta cryogenically freeze his head, decapitate him, or blow him up.
2. Anyone, including the main character, can die.
3. The past will come back to bite you in the ass. Whatever you think you know about the past, forget it. The past is not at rest! Any sins you think were committed in the past are about to break out and destroy you.
Scream 4
Rules to succesfully survive a horror movie remake:
1. The death scenes have to be way more extreme.
2. Unexpected is the new cliche.
3. Virgins can die now.
4. To be the new version you know 2.0, the killer should be filming the murders.
5. You have to have an opening sequence.
6. Don't fuck with the original.
7. If you want to survive in a modern day horror movie, you pretty much have to be gay.
